ordered subset problem

[John Trunek]

I need to obtain all the ordered subsets of containing 7 elements from a
list of 15 elements. From what I remember, the number of ordered sets is
given by the formula
numOfSets = 15! / (15-8)! = 32,432,400
Unfortunately, I'm not familiar with permutation algorithms. Could someone
please point me in the right direction to solve this problem?

Any good free combinatorics libraries that might have this functionality?
